J.J. Abrams Surprises Fans With Secret ‘Cloverfield’ Sequel (Video)

Despite his out-of-this-world success with “Star Wars: The Force Awakens,” J.J. Abrams still has a few surprises under his belt.

The director delighted moviegoers at the first screenings of Michael Bay‘s “13 Hours” on Thursday night with a trailer for a new Bad Robot/Abrams-produced movie titled “10 Cloverfield Lane.”

If that sounds familiar, that’s because the thriller is described by Paramount as a “blood relative” to the 2008 found-footage monster horror film “Cloverfield.”

While the existence of the film itself wasn’t a complete secret — having gone through the titles “The Cellar” and “Valencia” with stars Mary Elizabeth Winstead, John Goodman and John Gallagher, Jr. attached to it — all other details were a welcome shock to fans, especially the news that it will be released in two months.

“The idea came up a long time ago during production. We wanted to make it a blood relative of ‘Cloverfield,'” Abrams said in a statement to media via Paramount. “The idea was developed over time. We wanted to hold back the title for as long as possible.”

The 1:35-minute-long trailer sent social media into a frenzy when it popped on YouTube late Thursday night and quickly became a top trend on Twitter and Facebook.

“After a car accident, a young woman awakens in an underground cellar, where most of the action takes place. She fears she has been abducted by a survivalist, who tells her he saved her life and that a chemical attack has left the outside world uninhabitable. Uncertain what to believe, she decides she must escape, whatever dangers she may face outside.”
